Usually, a plurality of error categories are possible.Fig. 2 shows N classification by step 204,205 and 206 expressions.In in step 204,205 and 206 each, carry out the action that is exclusively used in this error category.Preferably, automatically perform these actions, and need not any input from the user.After finishing these actions, this method continues.The detail how method continues is at using.For example, at some error categories, this method can continue by turning back to the initialized A of expression execution.At other error categories, this method can newly be registered the B that attempts need not to reinitialize and continues by turning back to expression.More generally, described method can continue A at some conditions, and continues B at other conditions.In certain embodiments, at least one error category, this method continues by returning A, and at least one other error category, this method continues by returning B.

In certain embodiments, before returning B, realized for the first rollback time, realized for the second rollback time that before returning A the second rollback time was longer than for the first rollback time.In specific example, an error category of definition this method is no matter for what MIP registration to attempt, without any response.The method continues B, realizes for the first rollback time between each MIP registration is attempted.If at this specific error category, experienced pre-configured number of failed attempts, then this method continues A at second rollback after the time.In another specific example, an error category of this method relates to the timing error that loses by the error code indication that receives.When this mistake took place, this method was waiting for that second rollback returns A after the time.But under given conditions, this method is returned B at first rollback after the time.

Error category specific actions

Now, turn to Fig. 3, with according to the application's embodiment, a plurality of block diagram form of example error category specific actions are provided, show another complete retry method.In operation, mobile device 105 sends RRQM, so that register to MIP network 100.If mobile device 105 receives the successful RRPM of indication registration, then mobile device 105 will be registered in the registration duration.In step 301,, then carry out action if mobile device 105 does not receive any response.

Step 302,303 and 304 other example error category specific actions of expression.In step 302,, carry out action when receiving indication when losing the RRPM of timing error.In step 303, when receiving the response of the temporary transient network error of indication, carry out action.In step 304,, carry out action when receiving indication when wrong response is provided.In one embodiment, realize the error category specific actions of Overall Steps 301,302,303 and 304.In another embodiment, at least one in the error category specific actions of performing step 301 and the step 302,303 and 304.

After a while, by means of Fig. 4 and Fig. 5, provide the details of these example error category specific actions.

The user is provided with (User Profiles)

In certain embodiments, each mobile device 105 supports a plurality of users to be provided with.The example that the user is provided with is NAI (network access identifier), and each NAI is provided with and comprises user ID, password and shared secret.Mobile device 105 can switch between several NAI are provided with, but preferably, at given time, has only a NAI to be provided with effectively.

In certain embodiments, be provided with, safeguard retry history at each NAI.For example, retry history comprises the tabulation of the network that does not allow to set up the MIP session.For example, can not set up the MIP session if having the mobile device 105 that effective NAI is provided with " x ", then mobile device 105 will write down network and not allow NAI setting " x " to set up the MIP session in this tabulation.If provide specific NAI to be provided with again, then wiped its whole associated retry history.Again the example that provides comprises that clear and definite user initiates to provide trial or network to initiate to provide trial, as IOTA (aerial internet, Internet over the air).

In certain embodiments, the retry method of being carried out by mobile device 105 is that effective NAI is provided with and/or with this NAI the function of the retry history that is associated is set.Can be provided with at each, dispose different retry methods.Then, when receiving given RRP code, performed retry method is at received RRP code and effective setting and/or retry history.

Automatic retry method at initial registration

Now, turn to Fig. 4, show embodiment, the flow chart of the method for initial registration mobile device 105 on MIP network 100 according to the application.Carry out initial registration, so that set up PPP session at mobile device 105.In order to keep " always online " state, preferably, mobile device 105 triggers initial registration automatically, for example, and when it powers up or switches to another NAI and is provided with.When initiation MIP session was set up, described method began in step 401.In step 402,, FA 103 abilities are notified to mobile device 105 by receiving AAM from FA 103.Utilize this information, mobile device 105 is asked registration in step 403 by sending RRQM to FA 103.In step 404, mobile device 105 attempts receiving the RRPM from FA 103.If do not receive RRPM, then mobile device 105 will be overtime by determining whether to arrive maximum RRQM, determine whether it should resend RRQM.If still the maximum RRQM of no show is overtime, then mobile device 105 will resend RRQM after time delay.In step 406, mobile device 105 set RRQM retry back-off timers, and waited for that at mobile device 105 it is expired before step 403 resends RRQM.But if it is overtime to have reached maximum RRQM in step 405, then mobile device 105 is in step 407 set failure code, and proceeds to step 408.In step 408, mobile device 105 prepares to start anew retry MIP initial registration after time delay.Mobile device 105 is cancelled the PPP stack with the LCP termination messages, so that discharge resource, and set MIP retry back-off timer, and wait for that MIP retry back-off timer is expired.In case MIP retry back-off timer is expired, then, attempt the MIP initial registration again by being looped back to step 401.

If mobile device 105 receives RRPM in step 404, then whether the mobile device 105 RRP code determining to be included among the RRPM in step 409 represents the success of MIP initial registration.If successfully set up the MIP session.Then described method finishes in step 410, and mobile device 105 was registered in the duration given by the registration duration.The 105 storage registration duration of mobile device, be used for triggering and set up new registration procedure.If the MIP initial registration is success not, then mobile device 105 is carried out from step 411 action of starting process according to receiving the RRP code.

Lose stationary problem if mobile device 105 is determined to exist according to the RRP code in step 411, then lose stationary problem in step 414 addressing.Mobile device 105 loses coincidence counter by determine whether to exceed maximum in step 417, determines whether to have experienced the too much stationary problem that loses.Do not lose coincidence counter if exceed maximum yet, then mobile device 105 will resend RRQM in step 403.Otherwise mobile device 105 prepares to start anew retry initial registration after time delay.In step 415, mobile device 105 is cancelled the PPP stack with the LCP termination messages, set MIP retry back-off timer, and wait for that MIP retry back-off timer is expired.In case MIP retry back-off timer is expired, then, attempt the MIP initial registration again by being looped back to step 401.

If there is no lose stationary problem, then mobile device 105 determines in step 412 whether the RRP code represents temporary transient network error.If there is temporary transient network error, then mobile device 105 prepares to start anew retry initial registration in the step of having discussed 415 after time delay.

If there is no temporary transient network error, then mobile device 105 determines in step 413 whether the RRP code represents to provide mistake.Provide mistake if exist, then mobile device 105 prepares to start anew retry initial registration after time delay.In step 416, mobile device 105 is cancelled the PPP stack with the LCP termination messages, and record does not allow the network that inserts in tabulation, and waits for the network that does not find in the tabulation up to obtaining.In case completing steps 416 then by being looped back to step 401, is attempted the MIP initial registration again.

In certain embodiments, at being different from the error category set that in step 411,412 and 413, realizes, analyze the RRP code.Error category can be revised or increase to this method.More generally, retry method is operated as the function of the RRP code that receives.Preferably, automatically perform retry method, and need not input from the user.Should be appreciated that Fig. 4 is a specific embodiment, and multiple other embodiment are possible.After a while, will the detail of preferred error categories be discussed by means of Fig. 6.

At the automatic retry method of setting up new registration procedure

Now, turn to Fig. 5, show embodiment, on MIP network 100, set up new registration procedure the flow chart of the method for mobile device 105 according to the application.In this case, mobile device 105 has existing PPP session, and the home IP address of being distributed is (x.y.z.w).Mobile device 105 is from step 500, in the registration duration expired before, set up new registration procedure its home IP address (x.y.z.w) automatically.In step 503, mobile device 105 is by sending RRQM, and its home IP address (x.y.z.w) is set up new registration procedure in request.In typical scene, receive the RRP code in step 504, and set up new registration procedure successfully, and, mobile device 105 is set up new registration procedure another registration duration in step 510 at step 509 indication MIP.
